Sql 一个表中的聚合值在另一个表中更新

我想使用Update子句将聚合值从一个表插入到另一个表

SELECT Sum(1.0 * volume * speed) / Sum(volume) AS aggregated_speed 
FROM   traffic_data_replica 
GROUP  BY date, 
          id 
ORDER  BY date; 

我想在其他表中更新此值。这就是我尝试过的

UPDATE traffic_data_aggregated_lanes 
SET    traffic_data_aggregated_lanes.aggregated_speed = (SELECT 
              Sum(1.0 * volume * 
                  speed) / Sum(volume) AS aggregated_speed 
                                                         FROM 
       traffic_data_replica 
                                                         GROUP  BY date, 
                                                                   id 
                                                         ORDER  BY date); 

请帮助

关系不清楚。 有点

我们可以使用CTE，我也不确定数据。 所以我给了你们假设的结果

WITH CTE AS (
select t.Id,sum(1.0*volume*speed)/sum(volume) as aggregated_speed from  traffic_data_replica t 
group by date,id order by date
)
Select * FROM CTE
update traffic_data_aggregated_lanes    set traffic_data_aggregated_lanes.aggregated_sp= t.aggregated_speed From traffic_data_replica t
INNER JOIN CTE c ON C.Id = t.Id

我们可以用哪些列连接这两个表？请提供这些表的模式“这是我做的”和“这是我尝试过的”-和？怎么搞的？鉴于我们没有您的表或数据，我们不能自己尝试这些。你需要告诉我们发生了什么，你期望发生什么，区别是什么，等等。

WITH CTE AS (
select t.Id,sum(1.0*volume*speed)/sum(volume) as aggregated_speed from  traffic_data_replica t 
group by date,id order by date
)
Select * FROM CTE
update traffic_data_aggregated_lanes    set traffic_data_aggregated_lanes.aggregated_sp= t.aggregated_speed From traffic_data_replica t
INNER JOIN CTE c ON C.Id = t.Id
